Okay, I've now done this twice, and the result has been the same. I get a Giratina that is Adamant 16/23/20/9/5/24. This can only result from the seed F80F0262. This seed only occurs at frames 351, 429, 441, and 457. I just don't understand how this would happen. I simply ran the 10 coin tosses to confirm that I had hit the seed, opened up my Journal, turned to a page that had one of the catch lines, turned to an adjacent one that had that line, and rinsed and repeated. Does turning to a page that doesn't have one of these messages up the frame count? Thanks in advance.
EDIT: Of course they would still have the same seeds, but I still don't know why I'm not getting the right frame :(
Looks about right. A few things you should check: Are you sure you're hitting your seed? Are you sure you're using Method J instead of Method 1 to generate your Target Frame? Do you have any roaming legends?
Turning to a random journal page without a Defeated or Caught wild pokemon will not advance the RNG.
